I still don't get why this is. 99% of web search says it's to do with host lookup and adding the hostname to /etc/hosts fixes it. This doesn't seem to do anything for me.

The remaining 1% says to just strace the bastard.

Which I'd love to, but: only the first sudo invocation is slow, the rest is fast (so some sort of cache is likely in play).

But I need to run sudo to strace the sudo (I think?) and so the second invocation will just work no probs.

@deshipu that definitely helped, thanks!

But I also needed this:

strace -f -u <user> sudo ls

(didn't know about the -u parameter)

This definitely reproduces the issue and prints out a lot of stuff.

a non-update: I've spent some time digging through strace but I'm none-the-wiser.

SSH as root works great and whilst it feels a bit icky, it's not really any less secure than "regular user with sudo" as far as I can see.

(yes password login is disabled on the server, yes the SSH key is password-protected)

Still want to actually get to the bottom of this, I've got genuine work to do there and as Nanny Ogg wisely said:
